Divided and this application flled'0ctober 10, I

This invention relates to portable liquid treating apparatus, and is in part a division of my application Serial "Number 196,775, filed June 6, 1927.

The object of this invention is to rovide apparatus for treating various liqui s, such as milk, cream, etc., by means of a rotating coil or stirrer, which coil or stirring element is supplied with a temperature-changing me dium such as hot or cold liquid or gas. A further object is to construct a device in a portable and self-contained form, which will permit of its being readily and easily moved about from one container to another.

The present invention contemplates the use of an immersion heating or cooling element which may be submerged in a body of liquid to be treated and which is thereafter agitated to cause its radiation surface to come into contact with a maximum amount of the fluid recurrently within a minimum period of time, whereby greater heat transfer will take place than is accomplished when the liquid is,

substantially motionless with. relation to the heating or cooling medium, making the device particularly applicable for use in emulsifying, pasteurizing, cooling, and otherwise treating liquids to change their temperature.

One form which my invention may assume is exemplified in the following description and illustrated in the accompanying drawings, in which Fig. 1 shows an elevation, partly in section, of a form of the device, in which power is employed for rotating the coil;

Fig. 2 shows a side elevation of the upper portion of the device illustrated in Fig. 1;

Fig. 3 shows a sectional view, taken on the line V-V of Fig. 1.\

In the drawings, I show a portable apparatus embodying suitable power means for rotating a coil. This form of device includes a helical coil 120 carried at the lower end of a hollow shaft 121, which shaft at its upper end is connected to a suitable motor 122 and driven thereby. Said shaft and motor are supported by a thrust-bearing 123 which is provided with lugs 124 to rest upon the top of a container 125.

The hollow shaft contains within it a tu- Serial No. 311,555.

bular member 126 which forms the inlet for liquid may be admitted to the coil from a a distant source. Communicating with the outlet from the coil is a flexible pipe 129, also provided with valve means, and through which the steam or liquid which has circulated through the coil is discharged to any suitable point.

The motor as here shown is an electric motor, the power for operating which is supplied through conduits 130, although obviously a steam or water motor may be employed and flexible connections provided for supplying it with the necessary liquid or gas. Suitable handles 131 are provided for transporting and positioning the device.

The operation of this form of apparatus is the same as those described in the abovementioned application, except that no external supporting means are required, such as overhead tracks and the like, the entire device being adapted to be supported on the top of the container. As shown in Figs. 1 and 3, it is preferredto have the supporting legs 124 so arranged that the rotating coilfor the treating medium, a motor carried by the shaft for rotating the same, flexible connections leading to the shaft for supplying the treating medium thereto, and means on the shaft, engageable with a container, for

supporting the entire device during its operation.

2. An apparatus for treating liquids, comprising a coil through which a temperature- 'chan fng medium may be circulated, a shaft on w ich the coil is mounted, said shaft being provided with inlet and-outlet connections for the treating medium, a motor carried by the shaft for rotating the latter, flexible connections leading to the shaft, for supplying the treating medium thereto, flexible connections leadin to the motor for supplying a driving me iumthereto, a bearing on the shaft, and means on the bearing, engageable with a container, for supporting the entire device during its operation.
